Definitions

• base mold In most prior art injection molding systems, the entire base mold (also referred to as a "base mold") must be removed from the mold press to replace cavities and other components housed therein. Removing base molds is labor intensive and can shut down a mold press for extended amounts of time. Another problem with these systems is that modules and cavities are bolted together. Replacing or servicing modules and cavities is, therefore, both time consuming and tedious.
• Various embodiments of the present invention are directed to systems and methods for rapidly and accurately installing mold tooling into an injection molding press.
• One example embodiment of the system is comprised primarily of a carrier, tooling module, mold base, and carrier cart.
• the tooling module is constructed from standard tool plates and contains standard automatic injection tooling features (e.g., cooling lines, guided ejection, etc.) and is machined to allow the insertion of different cavity stacks to form plastic components of varying geometry.
• the plastic components can include features that previously would have been prohibitively expensive to incorporate in quick change tooling, notably threads (both internal and external).
• the modules are loaded into the carrier which is placed on a purpose built carrier cart that allows tooling modules to be assembled and secured before they are moved to the press.
• the carrier unit is employed for the purpose of installation and removal of the tooling module from the mold base, which remains in an injection molding press.
• the mold base is mounted semipermanently in the press and accepts the modules from the carrier unit.
• the carrier unit uses the tie bars of the press to position itself with reference to the mold base. Positioning on the tie bars facilitates the rapid removal of installed modules and rapid installation of new modules.

• FIGURE IA illustrates an exemplary module carrier 100 according to one embodiment of the present invention.
• module carrier 100 comprises tie bar mount 101, eye bolt 102, mount plate 103, air locks 104A- 104D, receiving channels 105 A and 105B, roller bearings 106, and carrier bumpers 107.
• the carrier unit is designed to rest on the tie bars of an injection molding press.
• Tie bar mount 101 is designed to rest across horizontally extended tie bars coupling the platen of an injection mold press. Tie bar mount 101 is tooled such that when the tie bar mount 101 lies across two horizontally extended tie bars, radius 108A cups one tie bar and radius 108B cups a second tie bar.
• Eye bolt 102 is coupled to tie bar mount 101 and allows module carrier 100 to be lifted by an overhead crane. As shown in FIGURE IA, eye bolt 102 may rotate around axis 109 and rotate around axis 110 to facilitate loading and unloading of modules onto the carrier cart and into the mold base, as will discussed in greater detail below. Although an eye bolt is shown by FIGURE IA, persons of ordinary skill will recognize that other mechanisms for lifting or hoisting (e.g., a ring or shackle) the module carrier can be coupled to the tie bar mount.
• other mechanisms for lifting or hoisting e.g., a ring or shackle
• Mount plate 103 is coupled to tie bar mount 101 and is designed to facilitate housing of tooling modules.
• a module is mounted to the face of module carrier 100 and held into place by air locks 104A-104D.
• air locks 104A-104D are Segan locks. Although Segan locks are shown, any type of hydraulic lock known in the art that is configured in a normally closed position (i.e., the locks open when air pressure is supplied by way of an air line and compressor, and the locks are closed when no air is supplied) may be employed in various embodiments of the present invention. Mounting of tooling modules to the module carrier is discussed in more detail below.
• Mount plate 103 is also designed to guide module carrier 100 onto receiving rails on a carrier cart (e.g., carrier cart 300 shown in FIGURE 3A) and, in some instances, receiving rails on a molding press.
• Mount plate 103 includes receiving channels 105 A and 105B on either side of mount plate 103.
• Receiving channels 105 A and 105B are designed to mate with receiving rails (e.g., receiving rails 304 and 305 shown in FIGURE 3A) and guide module carrier 100 into position.
• Mount plate 103 also includes a plurality of roller bearings 106 to facilitate mating of the receiving channels 105 A and 105B with receiving rails. In the embodiment illustrated by FIGURE 3 A, there are four sets of roller bearings 106 for each of receiving channels 105 A and 105B.
• carrier 100 When carrier 100 is used to insert modules into a base mold, carrier 100 is lifted by the eye bolt 102. Carrier 100 is then lowered into a mold press and tie bar mount 101 extends across the press and rests over the horizontal tie bars connecting the platen of the press.
• the configuration of tie bar mount 101 which is designed to fit over the tie bars between the platen on the mold press, ensures that the tooling modules carried by module carrier 100 are in the correct location so that the mold can be closed.
• the modules on carrier 100 are inserted into the ejection side of the mold. Once inserted, and as discussed in greater detail below, the molds are locked in place.
• Module carrier 100 shown in FIGURE IA also includes carrier bumpers 107.
• Bumpers 107 are coupled to mount plate 103 and are designed to ensure that module carrier 100 cannot be lowered into a press unless the mold base has been opened wide enough to accept module carrier 100. That is, if there is not enough clearance for the mold base to accept carrier 100, safety bumpers 107 will come to rest on the top of the mold base allowing a crane operator to halt lowering of carrier 100 before the full weight of module carrier 100 comes down onto the mold base.
• the carrier bumpers 107 shown in FIGURE IA include urethane feet 111.
• FIGURE IB illustrates another embodiment of module carrier 100. This illustration shows how the tie bar mount 101 can be designed to cup tie bars 112A and l l2B.
• FIGURE 2 illustrates an example tooling module 200 according to one embodiment of the present invention.
• Tooling module 200 is designed to precisely fit into the ejection side of a mold base (the placement of a module into a mold base will be discussed in greater detail below with respect to FIGURE 5A).
• Tooling module 200 is constructed from standard tool plates and contains standard automatic injection tooling features (e.g., cooling lines, guided ejections, etc.) and is designed to mate with the carrier unit to enable quick change out of tooling modules and, therefore, quick change of cavity stacks.
• the modules have guided ejector pins and roller bearings for accuracy in loading module 200.
• Tooling module 200 includes male portions of an air lock (e.g., a Segan lock) 201 A and 201B.
• Tooling module 200 is designed such that male air lock portions 20 IA and 20 IB align and mate with corresponding female air lock portions of a module carrier (e.g., elements 104A and 104B of module carrier 100 shown in FIGURE IA).
• Tooling module 200 is machined to allow the insertion of different cavity stacks to form plastic components of varying geometry.
• a hot runner system is illustrated. Plastic is injected from the injection/hot side of the mold base (e.g., 600 shown in FIGURE 6). Material comes into the face of the mold at 203 A and 203 B and is distributed through a runner system.
• the tooling module is designed to include male air lock portions on the tooling module face that is positioned against the injection side of a mold base (e.g., face 205). Male air lock portions could also be positioned at face 206.
• FIGURE 3 A illustrates an exemplary carrier cart 300 according to one embodiment of the present invention.
• Carrier cart 300 is used to store tooling modules and prepare tooling modules for insertion into a molding press.
• carrier cart 300 comprises a table 301 and support structure 302.
• Support structure 302 is fastened to table 301 and facilitates the storage of tooling modules (e.g., tooling module 200 shown in FIGURE 2) and loading and unloading of tooling modules onto carrier units (e.g., carrier unit 100 as shown in FIGURE IA).
• Support structure 302 comprises a plurality of carrier receiving units 303, which includes receiving rails 304 and 305, carrier rest stand 306, and supports 307A-307C.
• Receiving unit 303 is designed to receive a carrier unit (e.g., carrier unit 100 shown in FIGURE IA).
• Receiving rails 304 and 305 are fastened to supports 307 A- 307C and positioned to line up with and receive the receiving channels of a carrier unit (e.g., receiving channels 105A and 105B shown in FIGURE IA).
• Carrier rest stand 306 is fastened to table 301 and is designed so that a tooling module (e.g., tooling module 200 shown in FIGURE 2) will rest on carrier rest stand 306.
• carrier rest stand 306 comprises an aluminum base 308 fastened to table 301 with a polyurethane pad 309 on which a tool module rests.
• FIGURE 3A shows a carrier unit (e.g., module carrier 100 shown in FIGURE IA) mated with a carrier cart (e.g., carrier cart 300).
• the carrier unit houses one tooling module (e.g., tooling module 200 shown in FIGURE 2).
• FIGURE 3C shows a carrier unit housing two tooling modules mated with a carrier cart.
• the receiving rails on the carrier cart are identical to receiving rails on an injection molding press.
• the carrier cart may also include one or more storage shelves or bins for storing tools needed to change out, clean, or repair tooling modules or other injection molding tooling.
• the tool cart might also include wheels or slides so that the cart may be easily moved within the injection molding facility.
• it may be beneficial to prepare tooling modules in an area separate from the injection molding press (e.g., when injection molding is used to make medical devices, cleaning and preparation of tooling modules and cavities should occur outside of the clean room that houses the injection molding press).
• FIGURE 4 illustrates the ejection/cold side 400 of an exemplary mold base according to one embodiment of the present invention.
• Ejection side 400 contains standard automatic injection tooling features (e.g., cooling lines, guided elections, etc.) and is designed to mate with tooling modules (e.g., tooling module 200) to enable quick change out of tooling modules and, therefore, quick change of cavity stacks.
• Ejection side mold 400 is designed to house two tooling modules. In FIGURE 4, tooling modules 401 and 402 are housed in ejection side mold 400. Such tooling modules 401 and 402 are identical to tooling module 200 shown in FIGURE 2.
• Ejection side mold 400 is designed to mate with the injection/hot side of a mold base, which will be discussed in more detail below.
• Ejection side 400 also includes guide pins 403A- 403D.
• Guide pins 403A-403D guide the two mold halves (ejection side 400 and injection side 500) into alignment when the press is closed.
• the cavity portion of ejection side mold 400 which accepts modules (401 and 402) may have female air lock portions within the cavity for accepting and locking modules into place.
• Modules 401 and 402 would, in such a scenario, include male air lock portions on their face meeting the face of ejection mold 400.
• FIGURE 5 illustrates the injection/hot side 500 of a mold base according to one embodiment of the present invention.
• injection side 500 is designed to couple with ejection side 400.
• Guide in bushings 503A-503D are designed to mate with guide pins 403A-403D when the press is closed to ensure that the two mold halves (400 and 500) are properly aligned.
• Injection side 500 is the hot half of the mold. This means that the mold material is coming in from this side.
• the mold is closed (i.e., the ejection and injection halves are mated) and in operation, molten plastic is extruded through injection nipples 502A-502D into the ejector side 400 of the mold. Material comes into the face of the mold and is distributed through a runner system to a cavity (e.g., cavity 202 shown in FIGURE 2).
• Injection side 500 also includes an unwinder rack assembly 501 , which is used to create a thread on the inside of a part.
• core 504 When the mold is closed, core 504 is in an outward position, so the plastic forms around core 504.
• core 504 extends into cavity 404 (or cavity 202 as labeled in FIGURE 2) and the injected material collects in the cavity and surrounds core 504.
• the hydraulic unit drives a rack assembly that drives a gear and, in turn, unwinds the thread (it is on the same pitch as the thread). Core 504 unwinds itself from the molded part so the part can come out freely.
